Windows 7: Win7 boot issue after "trying" Ubuntu 12.10

Win7 boot issue after "trying" Ubuntu 12.10

I have a Lenovo X220 with a samsung msata ssd installed as the main drive. This drive has Windows 7 installed on it.
I was "trying" Ubuntu on a USB drive and apparently I screwed up my Windows 7 install because now Windows 7 will no longer boot(sticks at the starting windows screen). I used the boot-repair in Ubuntu(no idea why I did this) and this may have been the culprit(not positive though).

I have tried doing system repair with an installation disk and a repair disk made from another Windows 7 x64 OS and I always get an error message saying: This version of system recovery options is not compatible with the version of windows you are trying to repair...."

I'm fairly certain my broken Windows 7 is EFI and the other is not, so maybe that is the reason? Is there somewhere I can find a EFI repair disk?

I have accessed all of my files through Ubuntu, but I would prefer not re-installing everything if there is a way to fix this Windows 7 install.

If anyone could offer any advice I would greatly appreciate it!

Repair disc will need to made on a PC running Windows x64 in uEFI mode.
& also booted in uEFI mode.

I think I broke it...I've spent too much time trying to fix it unsuccessfully so I'm just going to format it and start over. Thanks for the help though!

Unplug all other HD's, Boot into Windows 7 DVD System Recovery Options or Windows 7 System Repair Disk to Mark Windows 7 or it's 100mb System Reserved Partition (preferred if you have it) Active.

Then run Startup Repair - Run up to 3 Separate Times until Windows 7 starts and it's boot partition holds the System Active flags.

If this fails when System Reserved partition is marked Active, move the Active flag to Windows 7 partition itself and then try the 3 repairs again.

Be aware that sometimes GRUB can corrupt Windows 7 beyond repair when on the same HD. If problems persist I would delete it completely and then for any future Linux Dual Boots use separate HD's booted only via BIOS, or Dual Boot - Windows 7 and Linux - Windows 7 Forums.

If all else fails it may be necessary to wipe the boot sector of interfering code using Diskpart Clean Command before Clean Reinstall - Factory OEM Windows 7 which steps are same for retail.
